Fits when a Marzzochi UpSideDown fork with a 40 series diameter inner pipe is installed. Safety through optimal suspension tuning! The progressive winding of the fork springs provides ideal functionality for road and racing use. At low compression, they offer maximum convenience due to the finest response (low breakaway torque). At the same time, if compressed further, the springs enable tight and precise driving for best traction properties and drift protection. To properly adjust the damper to the fork springs we recommend using Wilbers fork oil - the viscosity can vary from the original value.
